Description

TECHNICAL FIELD

[0001] The utility model relates to circuit design technical field especially relates to a parallel board, circuit board assembly and loop detection platform. BACKGROUND

[0002] Automobile wire harness must be detected before leaving factory. In the detection process, the special loop detection platform of automobile wire harness is needed, and the harness is inserted into the detection platform for power detection to identify whether the harness has open circuit, wrong road, short circuit and other problems. At the same time, whether the parts of the wire harness are complete and whether the air tightness of the air tight sheath meets the standard is also detected. Only when all the problems are corrected and the detection platform shows that the detection is qualified, the automobile wire harness is considered as qualified product.

[0003] On the detection platform, the plastic sheath of the wire harness is inserted into the detection module, and the hole position of each sheath corresponds to a needle position of the detection module. The number of hole positions of the sheath determines the number of needle positions of the detection module, and these needle positions correspond to the needle positions on the circuit board one by one.

[0004] However, due to the complex and various types of plastic sheaths of automobile wire harness, different function interfaces need to frequently replace different types of sheaths, which leads to the gradual increase of the number of detection modules on the detection platform. Each module has a fixed number of needle positions, and as the number of modules increases, the needle position resources of the detection platform become tight. If the number of detection circuit boards is increased to solve this problem, it may cause the voltage imbalance between the front and rear circuit boards due to voltage signal attenuation, thereby affecting the stable operation of the entire detection platform.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0029] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0030] As Figs. 1 to 3 shown, the parallel plate provided by the utility model embodiment includes: a substrate 101, at least one row of row mothers 102 and at least two rows of first row pins 103. Wherein, the row number of row mother 102 is less than the row number of first row pin 103. In the embodiment, row mother 102 is one row, and each row mother 102 has a jack. The first row pin 103 is four rows.

[0031] The busbars 102 are arranged on the first surface of the substrate 101, and the first pin rows 103 are arranged on the second surface of the substrate 101, and the extending direction of the first pin rows 103 is opposite to the extending direction of the busbars 102. The column number of each row of busbars 102 is equal to the column number of each row of first pin rows 103. Each column of busbars 102 is connected to the corresponding column number of first pin rows 103 through a wire. Each column of busbars 102 and the corresponding column number of first pin rows 103 are located on the same straight line. The distance between the adjacent two columns of busbars 102 is equal, and the distance between the adjacent two columns of first pin rows 103 is equal.

[0032] In the embodiment, the busbars 102 and the first pin rows 103 are all purchased components. The specification of the busbars 102 is 2.54 single-row round-hole busbar. The specification of the pin rows is 2.54 MM single-row pin row. The column number of the busbars 102 and the column number of the first pin rows 103 are both 64 columns. The distance between the adjacent two columns of busbars 102 is 2.54 millimeters. The distance between the adjacent two columns of first pin rows 103 is 2.54 millimeters.

[0033] Further, the busbars 102 and the first pin rows 103 are all welded on the substrate 101.

[0034] A circuit board assembly with a parallel board, the circuit board assembly 200 includes a circuit board 201 and the parallel board 100 described above. The circuit board 201 has at least one row of second pin rows 202, and the column number of the second pin rows 202 is equal to the column number of the busbars 102 of the parallel board 100.
